To all whom t .may concern:

Be it known that I, HENRY A.-RUDD, a

lcitizen of the United States, and resident of j This .invention relatesto splint drying means for match machines, having reference moreespecially to continuous machines 'wherein an endless carrierchainreceives the splints row by row and transports them through thematch making path, including a bath of impregnating material adapted torender the splints' nonglowing after the same, as finished matches, havebeen ignited and the flame extinguished.

The object of, my invention to provide, in such match machines, a.,drying structure into .and through which the wetrsplints, after theyhave been subjected to the'bath of impregnating material are carried andthereby eliectually dried in a relatively short space of time withoutmaterially increasing the length of the match machine or retard- .ingthe regular speed of travelj of the car' rier chain, asl will behereinafter described and claimed.

In'the drawings-Figure 1 is a longitudinal vertical section of a splintdrying strucf ture embodying my invention, the impregnating tank and aportion of the splint carrier chain being shown. Fig. 2 is a transversevertical .section of the structure, as o n the line 2 2 of Fig. 1. Fig.3 isa simllansection through. the chain inlet of the structure.

. f A designates a portion ofan endless carrier chain by means of'whichrows ofV splints are transported in' spaced relation to each otherthrough the match making path.

B designates atank in which the solution of impregnating material iscontained, which tank' is suitably supported beneath .the path of thecarrier chain. The track for this chain is appropriately constructed'(as at a') to eiect thevertical movement of theI traveling platesorsections 'of the chain in respect to the top of the tank after .thechain leaves the splint-inserting station of the match machine, and thusthe splints during their progress are periodically-dipped into andraised fromV the liquid contents of the .Y ator.

tank in order to effect the requisite impregnaiolof the splints.

esignates a splint-dryin structure lthrough which travels the chafignwith its wet impregnated splint-,s after' leaving the tank B. Thisdrying structure comprises an 'inverted U-shaped casing 1, a similarlyafford on one side of the radiator a drying chamber 3- through which thecarrier chain is directed with the splints pointing toward the radiatorin a manner to be exposed to heat; and toall'ord on the other side ofthe radiator an `air trunk 4 which communicates with the said chamber bymeans of a duct 5 at the foot of one ofthe limbs of the raditrunkandchamber lead respectively to the open alr, as at 6, and to an exhaustfan 7, wherebyfa continuous circulation of fresh air established; thatis to say, the air enters the mouth of the trunk, passes therethroughadolf the resulting vapors.

The radiator preferabl `vertical sections connect an arch section, .asshown, the whole having formed therein a chamber 8 for the efficientcomprises two dium. The outer faces of the radiator sections, that is,the faces Within the drying chamber,rare preferably. provided with amultiplicity of transversely-disposed ribs '9 which afford an increasedheat-radiating surface. The lower extremities of the vercap plates 10which are bolted to rails l1 supported by suitable posts 12. Thesecapplates are pierced by pipes 13,14, which communicate with the tiveends of the .radiator chamber 8; the pipes 13 at the inlet end of theradiatorV leadmgtoa suitable source of supply of steam, &c., and theother shaped heat radiator 2 supported therein to'.

HENRY A. RUDID, 0F BABBEBTN, OHIO, ASSIGNOB TO THE DIAMOND HATCH COIPANY,

The other adjacent endsof the 'air through the air trunk and splintchamber is at their top by Thus a continuous circulation of the heatingmedium is maintained within the radiator chamber.

The casing 1 is preferably a sheet metal structure bolted or otherwisesecured to the radiator therein contained, and is of proper .form anddimensions to afordin conjunction with the radiator, the dryin chamber 3and air trunk 4 above descri ed. The chain inlet portion of the chamber3 is connected with the outwardly curved flaring mouth of a conduit 15leading to the exhaust fan, the wall of the casing at such inlet portionbeing curved correspondingly with and connected to the mouth of theconduit in order that eiicient communication between such conduit andthe drying chamber may be had.

The inner side walls of the curved top of the drying chamber areprovided with a series of flanged rollers 16 for the support andguidance of the chain during its travel,

and the like walls of the vertical portions of the chamber are alsofurnished with guide bars 17 for the same purpose. Adjacent the outletopening 18 from the drying chamber is arranged a guide wheel 19 underwhich the carrier chain is drawn and thereby de ected to a horizontalpath as it leaves the chamber.

I claim- 1. In splint drying means for match machines having splintcarrier chains, a radiator, a casing therefor providing with the body ofthe radiator on the respective sides of the latter an air-trunk and adrying chamber, a connection between one end of the air trunk and oneend of the drying chamber, means for exhausting air from the other endof the drying chamber, and means for guiding he carrier chain throughthe drying cham- 2. In splint drying means for match machines havingsplint carrier chains, an inverted U-shaped casing, a similarly shapedradiator therein dividing the casing into two chambers, one of whichconstitutes an airtrunk and the other a splint-drying chamber, aconnection between a limb of the airtrunk and a limb of the dryingchamber, means for exhausting air from the other limb of the radiator, aseries of rollers arranged within the arch of the drying chamber for thesupport and guidance therein of the carrier-chain, and guides for the'Chain in t-he vertical lim-bs of said drying chamber.
